Abstract
An membrane electrode assembly for a fuel cell composed of a pair of electrode catalyst layers and an electrolyte membrane sandwiched between the electrode catalyst layers is configured so that the catalyst of at least one surface of the electrode catalyst layers enters in the electrolyte membrane whereby the electrode catalyst layer and the electrolyte membrane are unified with each other. In this configuration, no exfoliation occurs at the interface between the electrode catalyst layer and the electrolyte membrane, and the durability of the membrane electrode assembly can be increased even during the course of heat cycles.
